Abstract
Concrete column segments of the Powell Building (Reston, VA) exposed to the elements and wetted by precipitation were `cleaned' and roughened, but sheltered portions of the columns retained their smoothness and pollution accumulates, similar to observations for limestone, marble, and sandstone. Weathering effects on the columns were dominated by precipitation run-off and not the acidity of the precipitation. The process may be dry deposition of sulfur dioxide (SO2) and nitric oxides (NOx) that formed soluble salts in the presence of humid air or dew, salts that were removed by precipitation run-off.
